MAX8902A - Low-Noise 500mA LDO Regulators

Description

1.7V to 5.5V Input Voltage Range 0.6V to 5.3V Output Voltage Range 16µVRMS Output Noise, 10Hz to 100kHz 80µA Operating Supply Current 92dB PSRR at 5kHz Guaranteed 500mA Output Current ±1.5% Output Accuracy Over Load, Line, and Tem

Features

  • MAX8902A/MAX8902B The MAX8902A/MAX8902B low-noise linear regulators deliver up to 500mA of output current with only 16µVRMS of output noise in a 100kHz bandwidth. These regulators maintain their output voltage over a wide input range, requiring only 100mV of input-to-output headroom at full load. These LDOs maintain a low 80µA typical supply current, independent of the load current and dropout voltage. The regulator control circuitry includes a programmable soft-start circuit and short circuit.
